Customer Ratings & Reviews

Upgraded to gigabit internet, and my old Surfboard modem wasn't fast enough. Saw a thread on Reddit that recommended the Netgear modem over the Surfboard DOCSIS 3.1 one, so I decided to go for it. Installation was easy, I did have to call Comcast to have them add it to my account and after they sent the reset signal it started working right away. Easily hitting the gigabit speeds I'm paying for so I'm happy!

We recently changed internet carriers due to desperately needing faster speeds and we decided to try NETGEAR - CM1000 Ultra-High Speed to help maximize the upgrade and it has been excellent. It was initially challenging to break the $200 mark, but I would recommended it. It works great and we recently learned that in the next year or so many internet providers are going to be upgrading to 3.0 or higher and this unit will not require us to do any additional upgrades.

Easy to setup doubled speed no longer needed to have any extra signal boost products for the rest of the house

Saw immediate speed increase when I installed this modem. Easy to set up and get working. Great upgrade so far.

Easy to install and connect all my devices. Speed is as fast as my provider supply's.

If your provider supports it, get it! My service was constantly suffering from extreme drops in speed, 430 average to 20-30Mbps. After testing my router, I determined the issue to be the modem. I have had no issues with service any more and have even noticed an increase, 475 Mbps average now. Can't say this will be true for all but am pleased with its performance.

After 3 years, it's okay... The first two years, the modem worked without a hiccup. This past year though, I've had to power cycle it at least once per month with the occasional "reset" button. Which after looking at Netgear forums, this is a known issue. If it wasn't a pricer model, I'd have more forgiveness.

Works well easy to set up and the speeds are great

This modem rocks! For Xfinity gigabit service you need a docsis 3.1 modem. Xfinity has certified 3, an Arris SB8200, Motorola MB8600 and of the Netgear CM1000. I tried the Motorola MB8600 because it was cheaper. I decided on the Netgear. Activation was simple, I just call customer service and told them I had my own modem and would like it activated.You can also do it online, but I wanted to make sure everything was handled correctly.

So far this device is the best I've owned. It works great with my Luma routers and is definitely an easy setup. Since setup, I haven't experienced ant problems and is able to handle the multiple WIFI devices in the house without any bottle necking or slowness in internet connection. It was well worth the price. I highly recommend for anyone who needs a modem that can handle multiple internet connected devices.

I recently needed to replace an older modem/router combo unit with a more modern solution, and after doing my research, decided that this Netgear router would fit the need and match nicely with my high-end Netgear Nighthawk AC4000 wireless access point. I have not been disappointed. This modem was easy to install and has performed well for me so far.

Solid cable modem. Was able to replace providers modem with this one without fail. Wish the interface was a bit better, especially with what Netgear offers. Also wish there was an additional ethernet port. Overall, it’s a solid investment.

The modem is easy to install, easy to setup, not to expensive

I only have 200mbps DOCSIS 3.0 service at my house, but got this modem to make sure I was ready to upgrade to 1gbps+ once the price comes down. The backward compatibility seems to be great and now I will be ready for faster speeds in the future. This modem is easy to mount sideways if you remove the screws off the base it easily detaches. I put some little rubber feet on it so air flows better and it has been running fine on it's side.

This is the modem for those who want to just "set it and forget it". I bought this one because I don't want a bunch of bells and whistles — I want a simple modem with a minimum number of connectors that is easy to set up and is powerful and reliable. So far I am pleased with this choice. There has been one power outage since I installed this modem. My internet was back up and running within minutes after the power came back. With this modem being more advanced than the 6 year old modem I replaced, I have seen an increase in data speed, which is good because I am very demanding of my internet connection. It seems a bit expensive for such a simple modem, but the simplicity and reliability is worth it to me.

Great modem! Super fast cable modem!!! Great to setup! Easy to use!

A little bit pricey but the performance is worth it. Set up was very easy once you got past the drama of the Xfinity App. I am using it as a second network for the basement apartment and I am very pleased. Highly recommend Netgear Nighthawk 3.1

Just bought this for my gf and myself a motorola mb 8600 gig modem. Set up comcast Xfinity gig bit pro service on both and the netgear cm 1000 is still going strong and active while my motorola is having issues. I think its a comcast issue moreso but needless to say the netgear worked at my place initially before i bought the motorola and is still working well at her place while my motorola is not. I think its worth the money u save especially if u catch it on sale for $150 or so. The only downside is it does not have telephone capabilities.. u may wanna wait for the telephone capability modems that are docsis 3.1...

Product setup was easy and exactly as the instructions said it would be. Very happy with this item!

Replacing my older Netgear modem that was getting overwhelmed by the Xfinity internet speed increases plus it would lose connection too much. This one is much more stable and able to handle the higher speeds.
